Outside: Water-Purification Gear for Under $50
These will save you from drinking contaminated water—and shelling out a ton of money
Sawyer Squeeze Water Filter System
$40.00 from REI
Collect stream water in one of Sawyer’s 32-ounce pouches, then filter it through the hollow-fiber membrane to remove bacteria and protozoa. The pouches are collapsible (each weighs only three ounces) and reusable, and you can drink straight from the filter’s nozzle or pour the water into a bottle for later.
